Ok, in the Dolphin version of Rocket.Chat, a lot of the fields for the Dolphin OAuth section are hidden. I totally understand why for 3 of them, but - after playing with the unedited version - it is cool to be able to name your button whatever you like instead of being stuck with the arrow and box. Especially for those who may want to allow for more than one OAuth connection - such as Facebook, or Google, or even another Dolphin site. As well as being able to change the text color of the button.
